Ab initio and Rice–Ramsperger–Kassel–Marcus theories are carried out to study the potential energy surface and the energy‐dependent rate constants and branching ratios of the products for O( 1 D) + CH 3 CHF 2 reaction. Optimized geometries and vibrational frequencies have been obtained by MP2/6‐311G(d,p) method. The main products of the title reaction are CH 3 CFO + HF, CH 2 CFOH + HF, and CH 3 + CF 2 OH at lower collision energy; and CH 3 + CF 2 OH, CH 3 CF 2 + OH are the main products at higher collision energy. CHF 2 + CH 2 OH are the main products in the whole range of collision energy. © 2011 Wiley Periodicals, Inc. Int J Quantum Chem, 2012
